Significant frequencies modulo the orbital frequency to visualise the evidence for tidally perturbed modes. Top panel: the signature of multiplets expected from the theory of perturbed pulsation corresponding to different values of l and . Multiplets are plotted according to the tables in Smeyers (2005) and Balona (2018). Bottom panel: all significant frequencies from the pulsation analysis above 8 d⁻¹ modulo the orbital frequency. Frequencies are shown as black circles where filled circles indicate the frequencies with amplitudes above 165 ppm and open circles frequencies below that amplitude level. The frequencies are clearly split by the orbital frequencies and often reproduce signatures as expected from the theory.
